Latest Patents

One of Stelzer's latest patents is an engine air filter and sealing system. This innovative air induction system is designed to remove contaminants from intake air before it reaches the engine. The system features an assembly for filtering air, which is strategically mounted ahead of the engine, along with a duct that delivers the filtered air to the engine. A unique sealing system is incorporated to prevent unfiltered air from entering while allowing for the necessary movement of the engine relative to adjacent parts of the airframe as engine power settings change. This seal is engineered to withstand high pressures that can occur in the duct during engine operation.

Another significant patent by Stelzer is the control of the engine intake door. This system introduces an improved mechanism for managing an intake door within the air induction system. It includes a housing with an opening for receiving intake air and a power-activated door that pivots between closed and open positions. The linkages connecting the actuator cylinder to the door are designed to produce non-uniform movement across the cylinder's range of motion. This innovative design allows for precise control of the door's pivoting action, enhancing the overall efficiency of the air intake process.
